Blender wont start - New PC on windows 10
There is a bug thread regarding this. I would try out things listed in the first comment, especially trying out the latest build of 2.79 (I assume you have "clean" 2.79 from site downloads and thread seems to state that was resolved in builds after may 2018).
You could also try general solutions for this kind of error, like checking whether your blender folder is not read only and it could also happen when you have incorrect entry in PATH variable(thought it was an answer to java error).
